carryover that lubricates the piston rings and moving parts.
When this lubricating oil is exposed to normal air compressor
operating temperatures over time, the lubricating oil will form
varnish or carbon deposits. If the following maintenance check
are not performed, the air compressor piston rings will wear and
not seal correctly.

compressed air. Flying debris and dirt can cause personal
injury.
Shut off the engine.
Open the drain valve on the wet tank to release the system air
pressure.
